LetterStream is an online print-and-mail service for sending letters, postcards, certified mail, invoices, statements, and other document-based mailings from a web browser. Users upload documents, add recipient addresses, choose a mail type, and the platform handles printing, envelope insertion, postage, and delivery through USPS or FedEx options. The service is designed for both individual and business mailing workflows, including first-class letters, certified mail with tracking, postcards, and selected fast-shipping options.
The platform includes tools for building mailings step by step, reviewing proofs before submission, and managing mailing jobs through a dashboard. It also supports document uploads, CSV address files, reusable templates or stored documents, team access controls, and job history for review or reuse. Additional features include printing in black-and-white or full color, simple envelope and insert handling, certified mail tracking, and mailing support for business use cases such as billing, notices, ballots, healthcare communications, and donor mailings.
